[PATCH 1/3] drm/sun4i: frontend: Rework a bit the phase data

[Jernej Škrabec]

Hi!

Dne četrtek, 15. oktober 2020 ob 11:36:40 CEST je Maxime Ripard napisal(a):
> The scaler filter phase setup in the allwinner kernel has two different
> cases for setting up the scaler filter, the first one using different phase
> parameters for the two channels, and the second one reusing the first
> channel parameters on the second channel.
> 
> The allwinner kernel has a third option where the horizontal phase of the
> second channel will be set to a different value than the vertical one (and
> seems like it's the same value than one used on the first channel).
> However, that code path seems to never be taken, so we can ignore it for
> now, and it's essentially what we're doing so far as well.
> 
> Since we will have always the same values across each components of the
> filter setup for a given channel, we can simplify a bit our frontend
> structure by only storing the phase value we want to apply to a given
> channel.
